Socoder -> Blitz -> Color schemes by name

LostUser	I'm after a library or a list of color schemes by name rather than doing Color R,G,B. On this page: https://blitzbasic.com/codearcs/codearcs.php?code=2686 It has some examples, but I couldn't get it to work; also I'm wanting to keep it Object Orientated rather than just a list of constants. I am starting to write a basic Color type scheme manager so I can say Get_Color("Chocoloate") or something similar. Thanks.

Jayenkai	Constants, or a function. It's nice to think you can do it, but it's just not doable, IMO. Function ColByName(ColName$) Select Upper$(ColName$) Case "Red" Color 255,0,0 Case "Blue" Color 0,0,255 Case "Potato" Color 80,60,0 End Select End Function --v If it were part and parcel of the language, then fair enough, but it isn't.. if you want to return colors, you can do a large number, since Blitz can handle those at the third parameter of Color.. Function ColHexByName(ColName$) Select Upper$(ColName$) Case "Red" Return $FF0000 Case "Blue" Return $0000FF Case "Potato" Return $503C00 End Select End Function UseThis=ColHexByName("Red") Color 0,0,UseThis ; Where UseThis is a 24bit number, representing all three colour values, instead of a usual 8 bit one.. --v I suppose you could go through the hassle of making a UserLib for it, but it probably wouldn't be worth it. -=-=- ''Load, Next List!''

LostUser	That'll do. Thanks.

JL235	You should add an error for values not found, i.e. Function ColHexByName(ColName$) Select Upper$(ColName$) Case "Red" Return $FF0000 Case "Blue" Return $0000FF Case "Potato" Return $503C00 Default RuntimeError("Color not found, was given: " + ColName$) End Select End Function --v It's good practice as you'll get an error the moment you use an incorrect colour.
